Re: PCML novice quiestions

Have you considered using XMLSERVICE instead?​

youngiprofessionals.com/wiki/index.php/XMLSERVICE

XMLSERVICE doesn't suffer from a number of ailments that PCML+IWS does
(i.e. "Can't imagine being restricted to not being able to return anything
but 4-byte integers." this isn't an issue in XMLSERVICE)
